How would size, age, human disturbance, and vegetation structure affect bird communities of urban parks in different seasons?
Publication in refereed journal



摘要Parks are diversity hotspots in cities, and are generalized isolated "islands" in urban landscapes. However, there is a paucity of information on the avian community structure of urban parks in big cities in Southeast Asia, including Hong Kong which has more than 7 million people. This study therefore aimed to assess the influences of park attributes, human disturbance, and vegetation structure on species richness, diversity, total density, and species groups of breeding and wintering bird communities in Hong Kong. Bird communities of 30 parks were censused four times each season in 2010-2011 using point counting. Species richness and diversity were affected by park size in both seasons, and larger parks supported more species and higher diversity. In addition, species richness of wintering season was negatively affected by visitor rate. Total bird density increased with visitor rate, but only in the breeding season. Noise did not have significant impacts on species richness, diversity, and total density. Regarding the responses of species groups, number of resident species increased with park size in both seasons. Migrants, insectivores, and insectivore-frugivores were positively affected by park size, but negatively by visitor rate in the wintering season. However, omnivores in the breeding season increased with both park size and visitor rate. Granivores was the only feeding guild which was positively affected by noise and negatively by foliage height diversity in the wintering season. In conclusion, park size and visitor rate affected bird community structure, and different species groups had different responses to habitat factors in the two seasons.
